Maybe, but my V8 is more effective than your Prius, and has a higher capacity. 
I drive a 84 ford f 350 4wd, long bed, with a 460... I'm rolling about 6400 lbs empty, about 6800# the way I normally drive it.
I would run right thru a prius.
Its like the CHP officer told me years ago. who ever has the most lug nuts wins.

edit, I call small cars that like to pull right infront of me then slam on the brakes, "speed bumps" sooner or latter one of them is going to do that too me when I'm towing my 8000# dump trailer and I'm not going to be able to stop.
